DOM 常用到的功能模块

1. 从XML创建Document

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

DocumentBuilder db = dbf.newDocumentBuilder();

InputStream stream = new FileInputStream(filePath);Document doc = db.parse(stream);

2. 保存Document到文件 下面的代码将上面的doc 对象保存到由ouputFile指向的文件。

Transformer transformer = TransformerFactory.newInstance().newTransformer();

DOMSource source = new DOMSource(doc);

StreamResult result = new StreamResult(new File(ouputFile)); transformer.transform(source, result);
